3 lb. beef chuck steak, cut into 1 1/2 inch cubes (shoulder roast)
3/4 c. ketchup
2 tbsp. vinegar
Flour
1 1/2 tbsp. worcestershire sauce
4 tbsp. soy sauce
1/2 c. sugar
3/4 c. water
3 onions

Trim all the fat off the meat and cut into 1 1/2 inch cubes. Put a large scoop of flour into plastic bag and put the beef cubes on top. Shake so the flour coats all the beef cubes. Put the coated cubes into a large casserole or Dutch oven. Slice the 3 onions thin and place them over the beef. Mix together all the other ingredients and pour over the onions. Bake in a covered pan at 250 to 300 degrees for 3 hours.
